If not, why? Is it a copyright thing? I'm very interested in looking at what was there
Some of Franz Kafka's unfinished novels are still very readable so it's possible one of Dick's could be as well
For reference, from Wikipedia:
"In a 1976 interview, Dick said he planned to write a sequel novel to The Man in the High Castle: "And so there's no real ending on it. I like to regard it as an open ending. It will segue into a sequel sometime."<21> Dick said that he had "started several times to write a sequel",<22> but progressed little, because he was too disturbed by his original research for The Man in the High Castle and could not mentally bear "to go back and read about Nazis again".<22> He suggested that the sequel would be a collaboration with another author:
Somebody would have to come in and help me do a sequel to it. Someone who had the stomach for the stamina to think along those lines, to get into the head; if you're going to start writing about Reinhard Heydrich, for instance, you have to get into his face. Can you imagine getting into Reinhard Heydrich's face?<22>"
